What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Heavy metals (HMs) increasing rate in riverine water by human activities cause serious hazards to the health and sustainability of aquatic environments. The present study examines the accumulation of HMs (Ni, Mn, Pb, Cr) in water, sediments, and Labeo rohita fish of MRL and UCC, Chenab River Pakistan, and its implications on human health. Fish 36 specimens were collected with an average body weight of 170 ± 20 g. The results revealed that HM concentration in fish organs of MRL and UCC found in gills: Ni 8.57 ± .01, Mn 7.57 ± .01, Cr 5.20 ± .01, Pb 2.56 ± .01; Ni 8.20 ± .01, Mn 7.19 ± .01, Cr 4.78 ± .01, Pb 2.19 ± .01; liver: Mn 9.54 ± .01, Ni 6.98 ± .01, Cr 4.75 ± .01, Pb 4.66 ± .01; Mn 9.15 ± .01, Ni 6.48 ± .01, Pb 4.26 ± .01, Cr 4.22 ± .01; and muscle: Ni 4.94 ± .01, Mn 4.86 ± .02, Cr 1.73 ± .01, Pb 1.50 ± .01; Ni 4.48 ± .02, Mn 4.29 ± .01, Cr 1.28 ± .01, Pb 1.25 ± .02, respectively. BCF in gills, liver, and muscle found MN > Ni > Pb > Cr; Mn > Ni > Cr > Pb; Mn > Ni > Cr > Pb, respectively. THQ value for individual metal observed THQ < 1, which signifies no adverse effects, while the combined THQ value of investigated HMs found (1.094, 1.149) THQ > 1, which signifies expected adverse effects on human health during lifetime. HI values 2.23 and 2.16 observed HI > 1 indicated that consumption of studied fish contaminated with HMs cause a possible health risk. HM concentration was also observed higher than the permissible limits of TRV/USEPA/WHO in water and sediments. Therefore, consumption of investigated fish L. rohita can accumulate an estimated concentration of 1 × 14.10
